Are you living in a building that provides wifi to the residents for a fee? If so talk to the administrator.
Or do you mean to say that you have a broadband card from a cell carrier? If so, please provide more details. Who is the carrier? Is it a built-in card, USB, Mifi, PC card?
Or are you out in the country and using a wifi antenna on your roof that leads to a modem somewhere in the home?
Or even still, are you using a modem/gateway from your Internet provider which you are renting? I know a lot of providers will charge an extra $5 a month just because they're renting you a modem with the gateway built-in. Usually these aren't secured properly at all, which makes it more of a rip-off in my opinion.
The make and model of the laptop will help us too. If you have a modem/gateway or a separate router, the make and model of this will help too.
